CREAlVl-TESTING CHURN.-

SPECIFICATION forming part of Letters Patent No. 369,782, datedSeptember 13l 1887.

Application filed April 9, 1887. Serial No. 234,276. (No model.)

.To @ZZ whom/ it may concern.-

Be it known that I, FRANK B. FARGO, a citizen of the United States,residing at Lake Mills, in the county of Jefferson and State oflVisconsin, have invented new and useful Im provements in Cream-TestingGhurns, of which the following is a specification.

My invention relates to cream-testing churns; and it consists in theconstruction and combination of the parts thereof, which will be morefully hereinafter described, and pointed out in the claims.

One object of my invention is to facilitate the formation, collection,and ready transportation of the cream in bottles arranged in removablecases, without necessitating the removal or displacement of the saidbottles from the case until the butter is formed and separation takesplace.

A further object of my invention is to provide a creamtesting churnwherein the parts are rendered convenient by the adj ustability andremovability of the several parts, which are accessible at all points,and wherein the construction and operation of the parts are simple andeffective, strong and durable, easily handled and readily understood,positive in their ultimate result, and cheaply manufactured. I attainthese objects by the construction of churn illustrated in theaccompanying drawings, wherein like letters of reference indicatesimilar parts in the several views, and in which- Figure l is aperspective view of my irnproved cream-testing churn, showing theremovable drivers cases containing the bottles arranged in positiontherein. Fig. 2 is a top plan view of the same. Fig. 3 is a longitudinalvertical section on the line x x of Fig. 2. Fig. 4 is a detailperspective view of one of the cases removed from the frame-work of thechurn and as it is transported in the drivers cart. Fig. 5 is alongitudinal vertical section on the line y y of Fig. 4.

A indicates the side bars of the base-rest of the machine, which are ofsuitable configuration to accommodate the support and secure ment of theseveral parts of the churn entire. The two ends of the side bars, A A,are braced and`united by the transverse end bars, A A, suitably securedthereto. At the end of each of the side bars A, on the top portionthereof, knuckle-plates a a are secured, and inthe space between theknuckles thereof the lower ends of bars B B are inserted and held inpivotal connection therewith by pintles a', passing th rough theknuckles and the apertures formed in the lower inserted ends of the barsB. These bars B project upward, and are similarly connected toknuckle-plates c c, secured to the under side of the outer ends ofcross-bars C of a body, C. This frame C is rectangular in shape, and isgiven an oscillating motion through the hinged bars B.

The central parts of the side bars, A, of the base-fraine are curvedupward and have their highest portion at the central part of themachine. To the central top portion of the said bars A journal-boxes a2are secured, wherein a transverse shaft, B, has bearing, having abalance-wheel, Zi, on its one side and an operating-pulley, b2, on theopposite side. To the central cross-bar, C', on the under side thereof,a bifurcated casting, b", is secured, which is engaged by an eccentricmounted on the shaft B', and by which the body C entire is given anoscillating motion.

The body C is provided with side bars, G2 C2, transverse bars C3 C3,forming divisional compartments for the reception ofthe removabledrivers trays or cases D, and with crossbars C C', arranged and securedon the under side of the body entire, and are adapted to form base-restsfor the cases when in position in the body.

The body C may be constructed in such a manner as to provide any numberof divisional compartments for the reception of the cases D but, asillustrated, two such compartments are shown. These compartments ofthebody are adapted to receive a series of the cases D, which, whenthebutter has been formed, will be removed and replaced by others oflike form. I

The construction of a tray or case D is such that it will removablyconform to the corupartment wherein it is placed. The'two sides d dthereof are united by an end piece, d. At regular predeterminedintervals a series of cross-strips, d2, are arranged between the sides dof the case, which are providedwith a series of apertures, d3, for thereception of bottles or ICO jars E, containing cream which may have beengathered at different points. The bottoms of the bottles E rest againstcushion spiral springs e, arranged in the end piece, d', in a certainrelative position to the apertures d3 in the strips d2. As shown in Fig.5, two ro'ws of the bottles Eare arranged in the crossstrlps d2,- but itis obvious that as many as may be desired may be arranged therein, thenumber inserted in one case depending upon the dimensions of the machineentire and of the cases D. The bottles E are heldin a steady and stableposition in the cases D by the removable section D', which is clampedagainst the heads of the bottles through the medium of clamping-nuts,

l of suitable constructiomengaging with a short rod, d4, passing throughthe removable end section, D', and by means of a hoolgdformed with theinner end thereof, engaging with a tierod, d, passing through the center of the strips d2 and Athe end piece, d', and thereby secures thebottles in place against the cushioning effect of the springs c, whichpreclude the possibility of breakage of the bottles by a sudden shock orjolting in transportation, or from any other cause.

By myimproved form of construction of removable trays or cases thedelayoccasioned by the transfer of the bottles from the casesin the machineto the drivers cases is obviated, as in the use of my machine the traysor cases are taken from the driver after collection of the cream anddeposited in the machine and the butter formed.

The butter having been formed by the oscillatory movement of the body Gin the jars or bottles E, it isplaced in warm water and melted and thebutter-oil measured and the percentage of butter to the cream readilyascertained. Great care should be taken to prevent the loosening of thestoppers or corks of the bottles, so that no cream shall waste. By myconstruction I have endeavored to prevent the possibility of theloosening of the corks or caps of the jars.

It is evident that the machine constructed as herein described and shownmust of necessity facilitate the operation desired, preclude thepossibility of delay, and the utility is readily comprehensible andself-evident.

It is obvious that many minor changes in the construction andarrangementof the parts might be made and substituted for those shownand described without in the least departing from vthe nature andprinciple of my invention.

Having thus described my invention, I claimy 1. In a cream-testingchurn, the combination, with the supporting-frame, of a body pivnectingthe removable end section to the body of the case, a shaftjournaled inthe frame, eccentrics thereon, and bifurcated castings secured to anddepending from the under side of the body to engage the eccentrics,substantially as set forth.

2. In a cream-testing churn, the combination, with a horizontaloscillating body, C, comprising the side bars, G2, the bottomcross-bars, C', and the transverse cross-bars C3, the latter dividingthe frame or bodyintlo compartments, the base A, upon which the saidbody is mounted, the bars B, hinged to the corners of the oscillatingbody and to the base, and the removable cases D, fitted in thecompartments, and each comprising the side strips, d, united by an endstrip, d', the cross-strips d2, adjust` ing-bolts d6, the screw hooksand nuts, and the removable end section, D', resting directly yagainstthe heads of the bottles or jars, substantially as described.

3. The combination, with the body C of the base, comprising the sidebars A, having their highest point at the central part of the churn, andcross-bars A', connecting said side bars, ofthe strips B, hinged to thecorners of the body C and the base-frame, the shaft B', having bearingsin boxes secured to the top of the side bars A, at the center, andprovided with an eccentric portion, and the bifurcated casting b3,adapted to be engaged by saideeentric, substantially as described.

4.-. In a cream-testing churn, the combination, with the oscillatingbody C, having the compartments, as described, the removable cases D, tofit in the compartments, each comprising the side strips, d, the rigidAend strip, d', the perforated cross-strips d2 between the side strips,d, and through the perforations of which cross-strips the bottles pass,the springs e, seated on the end strip, d', and against the bottoms ofthe bottles, the removable end section, D', fitting between the sidestrips, d, and against the tops or corks of the bottles, and the adjusting-bolts d", passing through the case and' having nuts which bindonthe removable section D', to hold it in place, as set forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.

FRANK B. FARGO.
